The Influence of the Addition Element of Zn and Sr to Degradation Behavior of Pure Magnesium

The influence of the addition element of Zn and Sr to degradation behavior of pure magnesium simulated body fluid (SBF) had been studied. The results indicate that the corrosion destroy on the surface of pure magnesium was reduced markedly through the addition element of Zn and Sr. The average corrosion rate of pure magnesium, Mg-1.0Zn and Mg-4.0Zn-1.0Sr alloy is 1.526 g/(m2•h), 1.337 g/(m2•h) and 1.163 g/(m2•h), respectively.
